選(xuan)用(yong)(yong)(yong)適當的清(qing)(qing)(qing)洗(xi)(xi)劑對超聲波清(qing)(qing)(qing)洗(xi)(xi)效果影(ying)響較大。超聲清(qing)(qing)(qing)洗(xi)(xi)的作用(yong)(yong)(yong)機制主要是空化作用(yong)(yong)(yong),除物質的主要成分、油(you)垢或機體自身(shen)的機械雜質外,選(xuan)擇的清(qing)(qing)(qing)洗(xi)(xi)液(ye)必須考慮(lv)到清(qing)(qing)(qing)洗(xi)(xi)液(ye)的粘(zhan)度和(he)表面(mian)(mian)張力,才能起到空化作用(yong)(yong)(yong)。超聲清(qing)(qing)(qing)洗(xi)(xi)對清(qing)(qing)(qing)洗(xi)(xi)質量的要求(qiu)很高,經(jing)常(chang)使用(yong)(yong)(yong)幾種不同(tong)的清(qing)(qing)(qing)洗(xi)(xi)液(ye)在不同(tong)的槽中或依次進行,每一(yi)種清(qing)(qing)(qing)洗(xi)(xi)液(ye)的作用(yong)(yong)(yong)都不一(yi)樣。舉(ju)例來(lai)說(shuo),三氯乙烯、氫(qing)氧化鈉水(shui)溶液(ye)、合成洗(xi)(xi)滌(di)劑、水(shui)、酒精先后(hou)用(yong)(yong)(yong)來(lai)清(qing)(qing)(qing)洗(xi)(xi)光學(xue)元(yuan)件,丙酮及1*混合清(qing)(qing)(qing)洗(xi)(xi)液(ye),用(yong)(yong)(yong)來(lai)清(qing)(qing)(qing)洗(xi)(xi)半(ban)導(dao)體設備,用(yong)(yong)(yong)2*的清(qing)(qing)(qing)洗(xi)(xi)液(ye)和(he)去離子水(shui),經(jing)過多次清(qing)(qing)(qing)洗(xi)(xi),零件表面(mian)(mian)達到預期(qi)效果。
最常見的(de)方式就是將超(chao)聲(sheng)波(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)浸(jin)入(ru)槽(cao)內,在(zai)含有清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)的(de)超(chao)聲(sheng)波(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)槽(cao)內,由超(chao)聲(sheng)波(bo)換(huan)能(neng)器(qi)產生的(de)超(chao)聲(sheng)波(bo)振動由清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)槽(cao)底部(bu)(bu)輻(fu)射(she)到清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)中。尤其(qi)適(shi)用(yong)于中小型零(ling)件。對大(da)(da)小、重量較大(da)(da)的(de)零(ling)件,可采用(yong)局部(bu)(bu)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)的(de)方法(fa),即將零(ling)件浸(jin)入(ru)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)中清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),未清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)部(bu)(bu)分浸(jin)在(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)中,直(zhi)至完全清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)。另外一(yi)(yi)種方法(fa)是根(gen)據(ju)大(da)(da)尺寸零(ling)件形(xing)狀(zhuang)及局部(bu)(bu)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)的(de)需要,設計特(te)殊(shu)形(xing)狀(zhuang)的(de)超(chao)聲(sheng)換(huan)能(neng)器(qi),實現局部(bu)(bu)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)。對具(ju)有嚴格(ge)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)要求的(de)零(ling)件,在(zai)不(bu)同(tong)(tong)的(de)槽(cao)內采用(yong)多種不(bu)同(tong)(tong)的(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)進行(xing)超(chao)聲(sheng)波(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)。另外,還可以使用(yong)其(qi)他(ta)的(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)方法(fa),例(li)如(ru)加(jia)熱浸(jin)洗(xi)(xi)(xi)(xi)(xi),超(chao)聲(sheng)波(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)等(deng)。對含有特(te)厚油脂(zhi)的(de)零(ling)件,一(yi)(yi)般先用(yong)熱浸(jin)洗(xi)(xi)(xi)(xi)(xi)或高溫噴(pen)洗(xi)(xi)(xi)(xi)(xi),再用(yong)超(chao)聲(sheng)波(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)。對某些零(ling)件形(xing)狀(zhuang)過于復雜,如(ru)孔、孔角不(bu)一(yi)(yi)致等(deng),可采用(yong)一(yi)(yi)次多次清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),即在(zai)不(bu)同(tong)(tong)超(chao)聲(sheng)頻(pin)率下清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)。
清(qing)(qing)洗(xi)(xi)液(ye)的(de)超(chao)聲(sheng)(sheng)振動頻率對(dui)超(chao)聲(sheng)(sheng)清(qing)(qing)洗(xi)(xi)效果(guo)(guo)有很(hen)大(da)(da)的(de)影響(xiang),這(zhe)是因(yin)為它對(dui)空化(hua)的(de)影響(xiang)很(hen)大(da)(da)。通(tong)常用(yong)(yong)在20kHz左(zuo)右。約20kHz時(shi)容易產(chan)生(sheng)氣(qi)穴,清(qing)(qing)洗(xi)(xi)效果(guo)(guo)明顯(xian)。但是對(dui)表面要(yao)求高(gao)、孔徑或縫隙小的(de)產(chan)品,宜(yi)使(shi)用(yong)(yong)短波、能量集(ji)中(zhong)的(de)高(gao)頻超(chao)聲(sheng)(sheng)波清(qing)(qing)洗(xi)(xi),有時(shi)頻率可達800KHz。但高(gao)頻超(chao)聲(sheng)(sheng)振動在清(qing)(qing)洗(xi)(xi)液(ye)中(zhong)衰(shuai)減(jian)大(da)(da),作用(yong)(yong)距(ju)離短,空化(hua)強度小,清(qing)(qing)洗(xi)(xi)效率低。另外,由(you)于高(gao)頻指(zhi)向(xiang)性引起(qi)的(de)“陰影”區(qu)域,部分部件不(bu)能清(qing)(qing)潔。采用(yong)(yong)無頻率跟蹤超(chao)聲(sheng)(sheng)清(qing)(qing)洗(xi)(xi)裝置時(shi),需要(yao)對(dui)發生(sheng)器(qi)頻率進行調節,使(shi)其輸出(chu)信號的(de)頻率與傳感(gan)器(qi)的(de)固有振動頻率一(yi)致。這(zhe)時(shi),空泡效應最強。清(qing)(qing)潔液(ye)中(zhong)可見大(da)(da)量積(ji)聚(ju)的(de)白色物質。手指(zhi)頭像一(yi)根針一(yi)樣(yang)。
高(gao)功(gong)率(lv)密度(du)的(de)(de)超聲清(qing)洗(xi)(xi)是提高(gao)超聲清(qing)洗(xi)(xi)效(xiao)率(lv)的(de)(de)有效(xiao)途徑。然而(er),功(gong)率(lv)密度(du)過高(gao)會由于氣(qi)蝕(shi)過強(qiang)而(er)對(dui)工件(jian)表(biao)面(mian)造成侵(qin)蝕(shi)(即(ji)氣(qi)蝕(shi)腐(fu)蝕(shi)),對(dui)工件(jian)造成損害,尤其是對(dui)于有各種涂層的(de)(de)工件(jian)或(huo)鋁及鋁合金工件(jian)。能(neng)(neng)量密度(du)過大也不會產生飽和(he)效(xiao)應。對(dui)油污(wu)嚴重、形狀復雜、深孔盲(mang)孔的(de)(de)零(ling)件(jian),清(qing)洗(xi)(xi)槽要深、清(qing)洗(xi)(xi)液粘度(du)大、功(gong)率(lv)密度(du)大。高(gao)頻率(lv)超聲清(qing)洗(xi)(xi)功(gong)率(lv)密度(du)也很大。能(neng)(neng)量密度(du)可在用水或(huo)酒(jiu)精清(qing)洗(xi)(xi)或(huo)漂洗(xi)(xi)時(shi)降(jiang)低。
由(you)于(yu)清(qing)洗(xi)(xi)液(ye)的(de)(de)(de)空化程(cheng)度與溫(wen)度有關,溫(wen)度的(de)(de)(de)升高有利于(yu)汽蝕(shi),但蒸氣壓力也(ye)相應增大。溫(wen)度過高會使氣穴減(jian)少。所以必(bi)須(xu)保持一(yi)定(ding)的(de)(de)(de)溫(wen)度范圍(wei)。例(li)如(ru)水溶(rong)劑清(qing)洗(xi)(xi)液(ye)一(yi)般在45℃左右,三(san)氯(lv)乙烯(xi)清(qing)洗(xi)(xi)液(ye)約(yue)75℃,水約(yue)60℃。對揮發性(xing)和(he)易燃的(de)(de)(de)清(qing)洗(xi)(xi)液(ye),溫(wen)度不宜過高。
超聲清(qing)(qing)洗(xi)的(de)(de)(de)效果和質量取決(jue)于(yu)超聲清(qing)(qing)洗(xi)的(de)(de)(de)時(shi)(shi)間(jian)(jian)(jian)。對于(yu)清(qing)(qing)洗(xi)質量的(de)(de)(de)要(yao)(yao)(yao)求,時(shi)(shi)間(jian)(jian)(jian)過短。但是,零(ling)件(jian)(jian)表(biao)(biao)面氣(qi)蝕(shi)腐蝕(shi)嚴重,從(cong)而影響零(ling)件(jian)(jian)的(de)(de)(de)質量,延長使用(yong)壽命,不僅降低生產效率。油污染(ran)嚴重,形狀復雜(za)的(de)(de)(de)零(ling)件(jian)(jian),清(qing)(qing)洗(xi)時(shi)(shi)間(jian)(jian)(jian)要(yao)(yao)(yao)長。不同涂層的(de)(de)(de)鋁(lv)及鋁(lv)合金零(ling)件(jian)(jian)的(de)(de)(de)清(qing)(qing)洗(xi)時(shi)(shi)間(jian)(jian)(jian)不宜過長。一般說來,表(biao)(biao)面光潔度高的(de)(de)(de)零(ling)件(jian)(jian)的(de)(de)(de)油污較(jiao)少,清(qing)(qing)洗(xi)時(shi)(shi)間(jian)(jian)(jian)不宜過長。特(te)定的(de)(de)(de)清(qing)(qing)潔時(shi)(shi)間(jian)(jian)(jian)要(yao)(yao)(yao)通(tong)過實驗確定。
為改善清(qing)(qing)(qing)洗(xi)效果,并(bing)(bing)確保超(chao)聲波清(qing)(qing)(qing)洗(xi)裝(zhuang)(zhuang)置(zhi)的(de)(de)(de)正(zheng)常使(shi)(shi)(shi)用(yong),部(bu)件在(zai)清(qing)(qing)(qing)洗(xi)槽中的(de)(de)(de)位(wei)置(zhi)應引起重(zhong)視。開始(shi),要避免(mian)在(zai)超(chao)聲振(zhen)動(dong)輻射面(mian)直接(jie)擠壓零件,使(shi)(shi)(shi)輻射面(mian)無法(fa)產(chan)生(sheng)預期的(de)(de)(de)振(zhen)動(dong),導致清(qing)(qing)(qing)洗(xi)裝(zhuang)(zhuang)置(zhi)無法(fa)正(zheng)常工作。對較(jiao)重(zhong)的(de)(de)(de)部(bu)件尤其重(zhong)要。部(bu)件由專(zhuan)用(yong)工具吊在(zai)清(qing)(qing)(qing)洗(xi)槽內(nei),并(bing)(bing)盡(jin)可能接(jie)近表面(mian)。第二,關(guan)鍵的(de)(de)(de)清(qing)(qing)(qing)洗(xi)部(bu)位(wei)必須對準超(chao)聲波源(yuan)。三是要考慮清(qing)(qing)(qing)潔后污物能夠(gou)順利排放。第四(si),使(shi)(shi)(shi)清(qing)(qing)(qing)洗(xi)液(ye)在(zai)清(qing)(qing)(qing)洗(xi)槽內(nei)的(de)(de)(de)對流。使(shi)(shi)(shi)用(yong)循環連續(xu)補充(chong)清(qing)(qing)(qing)洗(xi)液(ye)的(de)(de)(de)方(fang)法(fa)時,進液(ye)速(su)度(du)不(bu)宜過(guo)快,否則(ze)由于補充(chong)的(de)(de)(de)清(qing)(qing)(qing)洗(xi)液(ye)中氣體較(jiao)多,氣穴就(jiu)會減弱(ruo)。
在盲孔(kong)清洗時(shi),應先(xian)在盲孔(kong)內(nei)注入清洗液(ye)(ye),然后將(jiang)盲孔(kong)對準超聲源。清潔時(shi),要(yao)始終(zhong)將(jiang)清洗液(ye)(ye)注入孔(kong)內(nei),以達到顯著的(de)效果。
超(chao)音(yin)波清(qing)(qing)洗(xi)槽應(ying)避免(mian)撞擊及快速冷(leng)卻加熱,以(yi)免(mian)損壞(huai)與傳感器的連接。對某些零件進行超(chao)聲清(qing)(qing)洗(xi)時,應(ying)進行消磁處理,否則(ze)殘余鐵(tie)屑不易(yi)清(qing)(qing)除。
超聲清(qing)洗質量檢(jian)查主要是檢(jian)查被清(qing)潔零件表面的污垢殘留(liu)。
